AC-DC Power Supply
PRODUCT OVERVIEW
The D1U4-W-1600-54-HBxC is a 1600W power factor corrected (PFC) front end power module intended for hot swap
redundant systems. There is a main output of 54VDC (floating with respect to chassis ground) and a 12VDC Standby/
bias output (that is present whenever the incoming AC source is applied.
The form factor is suitable for 1RU chassis enclosures and is designed to deliver reliable bulk DC power to servers,
workstations, storage systems, PoE switches or any 54VDC distributed power architecture requiring high power
density.
The high efficiency design supports speed controlled dual DC fans in a thermally optimized package that is self-protecting and able to auto recover from over-current and over-temperature events. Visual status information is provided
via front panel mounted LED indicators in addition to hardware logic signals and a PMBus™ management interface.

CURRENT SHARING NOTES
1. Main 54VDC Output: Analogue active share bus. The ISHARE bus (Pin B1) must be connected on all sharing modules.
It is not required that the SENSE signals are connected to the remote load for current share to operate correctly.
2. Up to eight (8) power modules can be connected in parallel (non-redundant) or N+1 configuration. The current share bus is analogue bi-directional (can source or sink
current from the ISHARE bus).
The voltage of the bus would measure 8VDC for a single power module at 100% load; for two (2) modules sharing a common load the ISHARE bus voltage would be 4V for
a perfect 50/50 current share scenario.
3. VSTANDBY output power modules can also be connected in parallel; however the combined available power is limited to that available from a single power module (12V;
2A; 24W) irrespective of the number of modules connected in parallel.
